Question 1

How does the find and replace tool work?

Accepted Answer

Paste your text, enter the word or phrase you want to find, and enter the replacement. Click Replace All and the tool will substitute every occurrence in your text and show how many replacements were made.

Question 2

What does the 'Case sensitive' option do?

Accepted Answer

When case sensitivity is enabled, the tool distinguishes between uppercase and lowercase letters. For example, searching for 'Hello' will not match 'hello'. When disabled, both are treated as the same.

Question 3

How do I use regex in the find field?

Accepted Answer

Enable the 'Use regex' checkbox and enter a valid JavaScript regular expression in the Find field. For example, entering \d+ will match any sequence of digits. If your regex is invalid, an error message will appear.

Question 4

What does 'Whole word only' mean?

Accepted Answer

When whole word matching is enabled, the tool only matches the search term when it appears as a complete word surrounded by non-word characters. For example, searching for 'cat' will match 'the cat sat' but not 'concatenate'.

Question 5

Is there a limit to the size of text I can process?

Accepted Answer

There is no hard limit. The tool processes text entirely in your browser. Very large texts (millions of characters) may be slower depending on your device, but typical use cases work instantly.
